Popped into Boots in Bletchley to get some deo, and spotted this Adidas Eau De Toilette "Deep Energy" reduced from £5.82 to £1.46. They also had another flavour ("Blue Challenge" I think) for £1.50. On top of that it was part of the 3 for 2 deal so was also able to get it with some deo.
It's still showing as full price online, and I'm afraid I don't know if it's any other store but hopefully someone else can confirm. First time I've actually found a deal which (hopefully!) isn't already posted. :)
When I tested it on my house mates, they said it smelt like the one normally wear, which is Clinique Happy for Men. Personally I don't think it's as subtle.
